From a Windsor Magazine article entitled “Animals That Are Soldiers” (Vol. 14):
“Jack,” the retriever dog of the 12th Lancers, also accompanied that regiment into active service. Jack is a thorough Lancer; he delights in the very sight of a lance, and barks joyously when he sees the regiment ready for the march, and promptly takes his place with the men in the ranks. It was said that, of all our cavalry, the Boers feared the Lancers most, and Jack certainly encouraged them in these views; one may well pity any enemy who tries to kill a 12th man with Jack in the neighbourhood. His hair is beautifully black and curly, and he is about as intelligent a retriever its anyone can find (pg. 264).
Jack was a “curly-coated retriever,” but I a bit cautious about giving him designation as a member of the curly-coated retriever breed. One of my goldens had a coat that was quite similar to this. Indeed, she very strongly resembled Jack in build and coat that I was somewhat shocked at the similarity. She was a very curly golden, who even had a partial water spaniel topknot!
The 12th Lancers were an active unit during the Second Boer War (1899-1902). I don’t know of how much use Jack would have been combat, but he certainly would have been good company. And if the unit had to shoot wild game for their dinner, they could always rely upon this intelligent retriever.
